I just bought a tear-down house, and needed to install a solid temporary power-source on the exterior of the building for general use around the property until we can demolish the house.
So, I bought a little 125A sub-panel at the local hardware store, and diverted the main house power (after the meter and main 100A disconnect breakers) away from the house breaker panel and into to this sub-panel, then I wired in two outlet circuits and mounted receptacles on the wall below the sub-panel.
The sub-panel did not come with a separate ground bus. I have read that you can only tie your grounds and neutrals together in one place (usually your main service entrance). But, without a separate ground bus in the sub-panel, I had to run my neutrals and grounds for my outlet circuits to the same bus. Will I be getting current returning over my outlet ground wires? Also, I had nowhere for my main (large-gauge) ground wire to bond to in the sub-panel.
Questions:
1. Do I need a separate ground bus in the sub panel?
2. Where do I connect the large-gauge ground wire? (right now I have it grounded to the casing with a junky connection).
3. In a proper installation, to what would I ground the panel casing to?
Any help from a professional electrician would be greatly appreaciated!
Thanks
